Description

Technical Field

[0001] The utility model relates to a pipeline detection device, belonging to the technical field of pipeline detection. Background Art

[0002] A pipeline mainly refers to a device formed by a pipe body and various connectors for transporting various solids, liquids and gases. The materials in the pipeline often move from one end with high pressure to the other end with low pressure or are transported due to gravity. In order to ensure the safety of pipeline transportation, regular pressure testing of the pipeline is required.

[0003] Currently available pressure testing devices can usually only detect whether there is a leak in the pipeline, but it is difficult to find the leak point of the pipeline. Therefore, after the detection, it is necessary to conduct a targeted re-inspection and search, which is troublesome, time-consuming and labor-intensive, and reduces the practicality of the pipeline detection device. Utility Model Content

[0004] The purpose of the utility model is to provide a pipeline detection device in order to solve the above-mentioned problem, which can easily find the leakage point of the pipeline while detecting the pipeline pressure, thereby avoiding the workers from checking and searching for the leakage point of the pipeline, thereby reducing the trouble of the workers and improving the practicality of the pipeline detection device.

[0005] The utility model achieves the above-mentioned purpose through the following technical scheme: a pipeline detection device, including a symmetrically arranged sealing box, a side surface of the sealing box is fixedly connected with an air bag ring, and the air bag ring is connected to the interior of the sealing box, a side surface of the sealing box is fixedly connected with an electromagnetic valve, and the other side surface of the sealing box is fixedly connected with an air pipe, the outer surface of the air pipe is provided with a pushing assembly, and one end of the air pipe is fixedly connected with an air distribution box, an air pump is fixedly installed on the upper surface of the air distribution box, and a pressure gauge is fixedly installed on the front side surface of the air distribution box.

[0006] Preferably, the pushing assembly includes a pushing ring, and the outer surface of the pushing ring is fixedly connected with a pushing rod, and both ends of the pushing rod can be extended by threaded splicing.

[0007] Preferably, an inner ring is provided on the side surface of the trachea, and a limiting ring is fixedly connected to the outer surface of the inner ring, and a groove is fixedly connected to one side surface of the limiting ring.

[0008] Preferably, a protection wheel is symmetrically fixedly mounted on the inner side of the inner ring, and the air pipe is located on the inner side of the protection wheel.

[0009] The beneficial effect of the utility model is that the utility model can conveniently find the leakage point of the pipeline while detecting the pipeline pressure through the setting of the sealing box, air bag ring and air distribution box, air pump, pressure gauge and pushing component, thereby avoiding the workers from checking and searching for the leakage point of the pipeline, thus reducing the trouble of the workers and improving the practicability of the pipeline detection device.

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] See also Figure 1-2 As shown, a pipeline detection device includes a symmetrically arranged sealing box 1, a side surface of the sealing box 1 is fixedly connected with an air bag ring 3, and the air bag ring 3 is communicated with the interior of the sealing box 1, a side surface of the sealing box 1 is fixedly connected with a solenoid valve 2, and the other side surface of the sealing box 1 is fixedly connected with an air pipe 14, the outer surface of the air pipe 14 is provided with a pushing assembly, and one end of the air pipe 14 is fixedly connected with an air distribution box 8, the upper surface of the air distribution box 8 is fixedly installed with an air pump 9, and the front side surface of the air distribution box 8 is fixedly installed with a pressure gauge 10.

[0015] As a technical optimization solution of the utility model, the pushing component includes a pushing ring 12, and the outer surface of the pushing ring 12 is fixedly connected with a pushing rod 5. Both ends of the pushing rod 5 can be extended by threaded splicing, which is convenient for pushing the sealing box 1 to move to different positions in the pipeline and narrowing the detection range.

[0016] As a technical optimization solution of the utility model, the side surface of the air pipe 14 is provided with an inner ring 6, and the outer surface of the inner ring 6 is fixedly connected with a limiting ring 7, and one side surface of the limiting ring 7 is fixedly connected with a card groove 11, which is convenient for clamping at both ends of the pipeline to limit the air pipe 14.

[0017] As a technical optimization solution of the utility model, a protection wheel 13 is symmetrically fixedly installed on the inner side of the inner ring 6, and the air pipe 14 is located on the inner side of the protection wheel 13, so it is convenient to protect the air pipe 14 and avoid direct contact and friction between the air pipe 14 and the pipeline.

[0018] When the utility model is in use, first, the sealing box 1 and the air bag ring 3 are inserted into the two ends of the pipeline, and then the air pump 9 is started to transport gas to the inside of the gas distribution box 8 through the air pump 9. At this time, the gas is poured into the interior of the sealing box 1 through the air pipe 14 and the air bag ring 3 is propped up. At the same time, the solenoid valve 2 is opened, so that the gas can enter the interior of the pipeline. When the air pressure inside the pipeline reaches a certain limit, the air pump 9 is turned off. At this time, the value of the pressure gauge 10 installed on the front surface of the gas distribution box 8 is observed, and then the pressure gauge 10 is observed again after a period of time. When the value of the pressure gauge 10 drops, it indicates that there is a leak in the pipeline. At this time, the worker pushes the sealing box 1 into the interior of the pipeline by pushing the push rod 5 in the assembly, thereby gradually narrowing the detection range of the pipeline, and thus determining the location of the pipeline leak.

[0019] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
